促淤工程中透空式六面体吊装质量控制探讨

Discussion on open-type hexahedron lifting quality control in silt promotion project

随着经济的快速发展,土地供需矛盾日趋紧张。为满足需求,促淤、圈围工程从高滩施工到深水施工的趋势日趋加快,借鉴南汇东滩促淤一期透空式六面体试验段的成功经验,减少促淤坝体施工对大宗块石的依赖性,在二期促淤工程中促淤堤采用透空式六面体坝体。为保障工程质量,杜绝或减少质量事故的发生,对透空式六面体的吊装施工工艺进行分析,理清吊装质量控制要点。

Contradiction between land supply and demand becomes increasingly nervous with the rapid development of economy. Silt promotion and enclosure projects are gradually accelerated from high beach construction to deep water construction in order to meet the demands. The successful experience of stage I open-type hexahedron experiment segment in Nanhui East Shoal silt promotion is adopted as reference for reducing the dependence of silt promotion dam construction on large stone blocks. Open-type hexahedron dam is adopted in silt promotion dams of stage II silt promotion projects. The lifting construction process of open-type hexahedron is analyzed in order to ensure the engineering quality and avoid or reduce quality accident. Control keys of listing quality are sorted.
